Device for Connecting a Fixed Line to an Absorber Pipe of a Solar-Thermal Power Plant

Abstract

The invention relates to a device for connecting a fixed line to an absorber pipe of a solar-thermal power plant, at least one solar collector being able to perform a pivot motion about the absorber pipe, characterized by a) a flexible pipe connection between the fixed line and the absorber pipe and a b) means for connecting the flexible pipeline to the absorber pipe with zero torque and/or zero force. Acceptable mobility of the solar collectors is thus ensured even at high temperatures and/or pressures.

1 - 10 . (canceled) 
     
     
         11 . A device for connecting a fixed line to an absorber pipe of a solar-thermal power plant, wherein a swivel movement of at least one solar collector can be performed around the absorber pipe, comprising:
 a) a flexible pipeline between the fixed line and the absorber pipe, and   b) a means for the torque-free and/or force-free connection of the flexible pipeline to the absorber pipe.   
     
     
         12 . The device according to  claim 11 , wherein the means for the torque-free connection includes a flexible pipeline whose first end is connected to the absorber pipe and whose second end is rotatably mounted, and wherein the axis of rotation of the second end is in alignment with the swivel axis of the at least one solar collector. 
     
     
         13 . The device according to  claim 11 , wherein the means for the torque-free connection includes a means for synchronizing the swivel movement of the flexible pipe connection with the swivel movement of the at least one solar collector. 
     
     
         14 . The device according to  claim 11 , wherein the swivel movement can be transmitted by a rigid connecting element between a swivel drive of the at least one solar collector and the flexible pipe connection. 
     
     
         15 . The device according to  claim 11 , wherein at one end the flexible pipe connection is coupled with a rotary union. 
     
     
         16 . The device according to  claim 11 , wherein the flexible pipe connection includes a metal hose. 
     
     
         17 . The device according to  claim 16 , wherein the metal hose constitutes a multilayer corrugated metal hose. 
     
     
         18 . The device according to  claim 11 , wherein the flexible pipe connection is coupled with a compensator system comprising at least one angular compensator, at least one universal compensator and/or at least one cardanic compensator, in particular three angular compensators. 
     
     
         19 . The device according to  claim 11 , wherein the flexible pipe connection is coupled with at least one lateral compensator. 
     
     
         20 . The device according to  claim 11 , further including at least one drive arranged in alignment with the axis of rotation of a rotary union.
